IMPROVEMENT IN APPARATUS FOR ROCKING C RADLES.

Specification forming part of Letters Patent No. 147,154, dated February 3, 1874; application filed December 16, 1872.

To all whom it may concern:

Be it known that I, DAVID NASH, of Haddenham, in the county of Buckingham, England, have invented certain Improvements in Means orApparatus for Rocking 0radles,of which the following is a specification:

The invention has for its object improvements in means or apparatus for rocking cradles. For this purpose, I suspend the cradle,

by means of rods, from two uprights, between which the cradle rocks or vibrates. On one of these uprights is fixed a suitable clockwork, which, by means of an escapement, gives an impulse to a pendulum or pendent lever, which, at its lower end, is connected to one of the rods supporting the cradle. Thus the era die becomes, as it were, a part of the pendulum, and when the clock-work is in action the cradle is continually rocked or vibrated. The upper ends of the rods are formed of springsteel to constitute frictionless and noiseless supports and, in order that my said invention may be more clearly understood and readily carried into effect, I will proceed, aided by the accompanying drawings, more fully to describe the same.

Figure 1 is a side view, and Fig. 2 is a crosssection, showing a cradle having my invention applied thereto.

a is the cradle, which, by means of rods 1), is supported from studs 0 fixed in the upper ends of the uprights d. The upper ends b of these pendent rods b I form of thin springsteel, so as to offer as little resistance as pos sible to the rocking of the cradle. One of these rods 1) I form with a slotted opening, b therein, Within which works a pin, 0, from the crutch e, which receives its impulses from the clock-work mechanism shown at f. This clock-work is shown in the drawings to be driven by a spring-barrel and inolosed in a box, 9; but the clock-work may be of any common or approved form, and applied in any convenient manner, these features of the illustration being unessential.

The action of the apparatus is as follows: When the clockwork is wound up, motion is given to the cradle by hand to start it in a similar way to an ordinary pendulum, and the rocking of the cradle is continued by the impulses given thereto from the clockwork until it is purposely stopped, or the clock-work has run down, the cradle simply taking the place of an ordinary pendulum.

Having thus described the nature of my said invention, and the mode in which I carry the same into effect, I would have it understood that what I claim is- The combination of the clockwork f, the crutch or swinging lever c, and the slotted pendulum-rods b with the supports b c, uprights (Z, and cradle a, substantially as specified.

hi DAVID NASH.
